The paper develops an efficiency numerical algorithm for calculation of static characteristics of a long ocean mining pipe hanging from the ship. The algorithm is based on an asymptotic theory of ordinary differential equations, namely, on Tupchiev’s method of solution of singularly perturbed boundary-value problems. The developed algorithm is shown to be fairly universal, providing fast and highly accurate computation. Prospects of asymptotic methods for long ocean pipe motion modeling are noted. Examples are given of a pipe static analysis confirming an efficiency of the developed procedure.
